Lithium Bearing Pegmatites Identified at West Pilbara Joint Venture Project
Highlights:
· Lithium bearing pegmatites identified within Osborne Joint
Venture (Artemis 49% interest)
· Significant assays:
o 1.8% Li2O from Sample No 23GT11-041
o 1.7% Li2O from Sample No 23GT11-042
o 1.58% Li2O from Sample No 23GT11-039
· Mineralised trend identified extends within JV tenure
· Field activities are currently underway in the search for lithium
bearing pegmatites and dykes on Artemis tenements
· Artemis tenements E47/1746 and E47/1797 adjoins the JV project
· Review of historic geochemical soils sampling data on the Artemis
tenements indicates elevated lithium and lithium pathfinder elements
Artemis Resources Limited (ASX: ARV) (Artemis or Company) is pleased to advise
that lithium pegmatites have been identified on the Osborne Joint Venture
(Greentech Metals Ltd 51% / Artemis Resources 49%).
As announced by GreenTech Metals Limited (ASX: GRE) in the ASX release of 7
July 2023 1 (#_ftn1) , GreenTech announced that the Kobe Lithium Prospect
extends into the Joint Venture exploration licence E47/3719. The mineralised
trend defined to date within JV tenure is shown in Figure 1 below. High tenor
lithium assays received within the project area include:
1.8% Li2O from Sample No 23GT11-041
· 1.7% Li2O from Sample No 23GT11-042
· 1.58% Li2O from Sample No 23GT11-039
Further work is planned on the Joint Venture tenement with sampling and
mapping aimed at identifying the full extent of the mineralised pegmatite zone
and the consistency of the lithium minerology and grade. Preparations have
commenced to enable a maiden drilling program as soon as all approvals are
received.

Artemis West Pilbara exploration
As part of the Company's West Pilbara exploration review and field work,
Artemis has also commenced a review and assessment of lithium prospectivity in
its 100% owned tenure. Artemis currently controls approximately 144km2 in the
West Pilbara adjacent to the lithium find.
Artemis has commenced a review of extensive soils database and commissioning
of third party Consultants to process detailed satellite data.
A review of historic geochemical soils sampling data indicates elevated
lithium and lithium pathfinder elements on Artemis tenements E47/1746 and
E47/1797 adjacent to JV project.
An initial field reconnaissance programme has been completed which involved
the investigation of areas of interest defined by soils data, with a number of
rock samples taken and forwarded for analysis. A second field programme will
be undertaken this week to follow up on various locations of interest.
Artemis holds a 9.67% interest in GreenTech Metals Limited (ASX: GRE) which at
7 July 2023 has a value of ~ $4 million.
End.
This announcement was approved for release by the Board.

and igneous complexes that have been variously affected by several tectonic
events. The easterly to east-north easterly trending Sholl Shear Zone (SSZ) is
a boundary for the regional rock packages. Metamorphic grade is higher to the
